Medium-power phase control thyristors rated at 50A

America Semiconductor has announced the 50RIA Series of medium-power phase control thyristors. Supplied in an industry-standard TO-65 package, the silicon controlled rectifiers (SCRs) feature a current rating of 50A. The robust vacuum-wielded devices offer exceptional dynamic characteristics, superior surge capabilities, low thermal resistance and high dl/dt and dV/dt capabilities. The 50A stud thyristors are ideal for employment in an array of high-reliability consumer and industrial applications. They are commonly specified for phase control in converters, as well as in lighting, temperature and speed control circuits. Parts are also highly appropriate for use in battery chargers and regulated power supplies. The SCRs are available in 9 voltages with types up to 1600V VDRM/VRRM. Maximum gate trigger current is 100 mA, whereas maximum gate trigger voltage is 2V. Maximum RMS on-state current is 80A. The thyristors support a maximum operating junction and storage temperature range of -40C to 125C. Metric threads versions are available, says the company.
